说明
paccache is a cache cleaning utility for pacman, the Arch Linux package manager. It removes old package versions from the pacman cache directory (/var/cache/pacman/pkg/) while preserving recent versions for potential rollbacks. By default, it keeps the 3 most recent versions of each package. This helps reclaim disk space while maintaining the ability to downgrade packages if needed. The tool can target all cached packages or only those no longer installed on the system.
